Is there a way to move an open application from one work space to another without closing it

Want to do a split screen situation but the windows are in different workspaces

Do you mean moving windows from one workspace to another?

Various keyboard shortcuts available in Menu - Keyboard - you can also define your own keyboard shortcuts to move windows to specific workspaces.

This shorcut does not moves my windows one workspace “down” or “up”

Sadly

Workspaces are left to right in budgie.

Oh, that makes sense.

Does moving to workspace 1 or 2 works?

Yes. 1 to 4 on that screen. 5 to 9 via dconf

Thank you very much!
